AVItools is a Mac OS X application used for the creation and editing of AVI videos. It is an offshoot of another application called MKVtools, so if you are familiar with its operation, you should be comfortable using AVItools.
As the name might imply, AVItools is a graphical interface for a variety of tools useful for processing video files. Mencoder and Mplayer do the brunt of the work. Limitations to AVItools' capabilities are most often due to limitations with these applications. When you open a video file in AVItools, you will be presented with a list of video, audio and subtitle tracks contained in the file. Sometimes there will be enough information for you to determine what each track represents. If not, you can select a video and an audio track (and optionally a subtitle track) to preview the tracks in an mplayer window. Once you've determined which tracks you are interested in, you can either convert the tracks into an AVI video, or you can extract the tracks individually to manipulate in your favorite video application. You also can edit AVI files by either splitting or joining videos.
AVItools is Intel-only (64-bit) and requires Mac OS X 10.7.x or later. It has been tested on a MacBook Pro and a Mac Pro with no known issues.
